CIDCO — Indiscriminate Felling of trees

On 30th June, 2015, In sector 11, Kharghar, there has been vast cutting of trees without any regulation. The CIDCO employees/contractors are cutting down all trees to the trunk and are claiming that they are only "trimming" the tree. To my knowledge, such cutting of trees is not permissible by the forest department. The concerned department of CIDCO claims that they have not given any sort of permission and have told us to contact somebody else. Nobody is taking responsibility. Is there anybody to take note and take action? Enclosure: I have attached photographs of a tree already cut and the workers cutting other trees.
